/* /learn-named-clinic-sources-internal: its own sheet, loaded after site.css.
   A reference page: the public sources behind the four clinic comparisons.
   One idea runs it: a clinic's name leads to the documents under it. The hero
   draws that as a contents list with a leader to each clinic's sources, and
   each row of the ledger carries a small drawing of the kind of document it
   is. Sister page: /learn-mexico-sources-claims-internal (same hand).
   Script: scripts/learn-named-clinic-sources-internal.js. With that script
   absent every part is visible, every link still jumps, and the row a link
   lands on is still marked (:target). */
